DIY Tracking device

Hi I'm looking to use traccar with a raspberry pi pico and a gps/gprs unit to create a custom device tracker. this will all be done in rust

i have a few questions though.

what is the recommend protocol to connect to the traccar server with. ideally with a low data usage

i will also be taking a full diagnosis check all the time from the car can bus which will be uploaded when i get home and it connects to wifi. should this be stored in traccar or just use a another database.

does anyone have a public repo with something similar i can look at.

Cheers

I have integrated trackers where the data is collected in a proprietary system, and post the position data to Traccar via the OSMAnd protocol.

Quite simple: follow the instructions at https://www.traccar.org/osmand/

I also have other data we collect, that is stored / analyzed in a separate DB and application.

Note that you can add other attributes to the given example, so that is another possibility

thanks for the info. osmand does look like a easy way to impl traccar. and i think i will go separate as that will allow me more freedom.

if you dont mind me asking half often to u send gps updates. like every second or what.

We use 30 seconds when the device is moving, as driven by the source system. It's a balance of electric consumption and cell data usage vs more accurate tracking. Our trackers go into sleep mode about 5 minutes after the vehicle stops moving, with a keep alive every few hours.

thanks for the help
